Exploring the Master
Arpeggiator
PX-7’s multi-channel Pattern Generator/Arpeggiator is one of the greatest
features ever put in a synth. Let’s explore the Master Arpeggiator.
 To Arpeggiate a Single Preset:
1. Select a preset. Note that the factory presets all have prefixes which
describe the type of sound. For this investigation it might be best to
choose a preset with the prefix “arp,” for arpeggiator. These presets are
optimized for use with the arpeggiator.
2. Set the Arp parameter in the main preset selection screen to “M” for
Master Arpeggiator.
3. Press the Arp button in the Edit section of the front panel to access the
master Arpeggiator menu, then use the data entry control to scroll to
the screen shown below.
4. Make sure the arpeggiator Status is “on.” Play the keyboard to start
arpeggiating.

arpeggiator parameters.
5. Press either cursor key repeatedly to move the cursor below the Status
field.
6. Turn the data entry control clockwise one click. The Mode screen
appears.
7. Use the cursor keys to move the cursor to the Mode field (up, down, up/
down, forw asgn, backw asgn, forw/backw, random, pattern). Try out
the different modes as you play the keyboard.
8. Move the cursor back to the lower left position and explore the other
parameters. The Note Value parameter changes the rate of the arpeggios.
By the way, note value is a divisor based on the Master Tempo. Try
changing the tempo, but come right back.
9. Let’s check out the pattern generator. Go back to the Mode screen and
set the mode to “Pattern”.
10. Now advance to the Pattern screen (shown below) and move the cursor
to the Pattern Number field (the second field from the left).
